Effect of sources and doses of Sulphur and Boron application on Yield, nutrient content and nutrient uptake of Groundnut (Arachis hypogea L.)

The field experiment was carried out at Regional Research and TechnologyTransfer Station (OUAT), Mahisapat of Dhenkanal district during kharif season of 2014 and2015 to study the “Effect of different sources and doses of Sulphur and Boron application onYield, nutrient content and nutrient uptake of Groundnut under Mid Central Table Land zoneof Odisha”. The experiment was laid out in randomized block design with three replicationscomprising of seven treatments T1 - Soil Test Based Fertilizer Recommendation (STBFR), T2- STBFR + Sulphur @ 20kg /ha from Gypsum Source, T3 – STBFR + Sulphur @ 40kg /hafrom Gypsum Source, T4 - STBFR + Sulphur @ 20kg /ha from Gypsum Source + sprayingof Borax @ 0.3% twice before and after flowering, T5 - STBFR + Sulphur @ 20kg /ha fromBentonite Sulphur Source, T6 - STBFR + Sulphur @ 40kg /ha from Bentonite SulphurSource, T7 - STBFR + Sulphur @ 20kg /ha from Bentonite Sulphur Source + Spraying ofBorax @ 0.3% twice before and after flowering. It was revealed that T7 recordedsignificantly higher pod yield (17.14 q ha-1), 100 kernel weight (38.93 g) and shelling percent(66.00) followed by T4 with pod yield (15.80 q ha-1), 100 kernel weight (37.60 g) and shellingpercent (65.10). T7 was superior over T1 with the yield advantage of 24.2 % and B: C (2.10).The Concentration of nutrient N, P, K, S and B in the harvested pod was also found highest inT7 i.e. 4.34 %, 0.70% , 0.88 %, 0.39% and 17.77 mgkg-1 followed by T4 having concentrationof 4.26% ,0.66 % , 0.83 %, 0.35% and 17.23 mgkg-1 respectively. The same treatment T7 alsorecorded higher uptake of N, P ,K, S and B in pod with 79.47, 9.20 ,19.83,6.23 kg ha-1 and31.43 g ha-1 respectively.
